Color Balance- is a finesse control. It makes subtle color cast
changes within the highlights, mid-tones, or shadows of an image. It demonstrates
the relative nature of color very well, as it presents three sliders that
represent the different color polarities. Move the slider towards the red,
and conversely away from the cyan, and see the effect it has in real time.

Brightness/Contrast-, it doesn't get any more basic that this. One
slider controls the brightness, the other the contrast. In fairness, this
one doesn't even deserve to be called a color control, since it does not
allow specific color changes. Move past this control as fast as you can.
